Thanks for these suggestions. I will send out a note to my class and
ask them to document their configurations and their version as well as
what they were doing when/if crashes occur. I will also request that
all crashes are reported if possible (I'm not sure that sending a
report was possible when my crashes occurred but maybe my memory is
I am heartened to hear that others are not experiencing crashes. It
gives me hope that this will be solvable, and also makes me wonder if
we are doing something boneheaded (e.g., everyone in my class is using
the same RProfile.site file... maybe something screwy in there...
etc). More to come...
PS - as this thread has been building, so has a thread among the profs
here at CU about this issue. One prof claims no crashes, another says
it crashes every time they did a particular assignment...
